5 Key Definitions for the Assessment Degraded land - state of land which results from the persistent decline or loss in biodiversity, ecosystem functions and services that cannot fully recover unaided within decadal time scales. Land degradation- myriad of processes that drive the decline or loss in biodiversity, ecosystem functions or services, and includes the degradation of freshwater and coastal ecosystems which are closely interconnected with terrestrial ecosystems Restoration is defined as any intentional activity that initiates or accelerates the recovery of an ecosystem from a degraded state, and this includes the halting or reduction of ongoing degradation processes. The term rehabilitation is used to refer to activities that seek to restore important ecosystem functions (e.g. nutrient cycling, water flow) but may fall short of fully restoring the biotic community to its pre-degradation state.

6 Assessment Outline 1. Concepts and Perceptions of Land Degradation and Restoration 2. Direct and Indirect Drivers of Land Degradation 3. Land Degradation Processes and Changes in Biodiversity and Ecosystem Structure and Functioning 4. Land Degradation associated with Changes in Nature s Benefits to People and Impacts on Quality of Life 5. Responses to control land degradation and rehabilitate and restore degraded land 6. Decision support to address land degradation and support rehabilitation and restoration of degraded land 7. Scenarios of Land Degradation, Rehabilitation and Restoration 6

7 Contributions of the Study 1. Increasing awareness and understanding of the drivers of land degradation (LD) 2. A more comprehensive conceptual framework and knowledge base 3. Creating a framework for embedding a systems approach to understanding, monitoring and acting against LD 4. Identifying the most effective methods and approaches for assessing, avoiding, minimizing LD, and responses to restore/recover/rehabilitate 5. Decision support to help build capacity 6. Identifying priority knowledge gaps 7

8 IPBES Land Degradation and Restoration Assessment Wide range of sources for reviewing: all relevant articles, books, national and international assessments government, United Nations, national and international NGO reports and indigenous and local knowledge need for strong vetting and quality check process. 8
